Document Type and Number:
WIPO Patent Application WO/2022/077875
Kind Code:
A1
Abstract:
An electron beam oscilloscope having improved temporal resolution, and a measurement system thereof. The oscilloscope has a high-voltage pulse generator (105) having a positive output end connected to a microstrip cathode (101). A negative output end of the high-voltage pulse generator (105) is connected to an MCP image intensifier tube (104). An anode mesh (102) is grounded. The microstrip cathode (101), the anode mesh (102), the MCP image intensifier tube (104), and a CCD are sequentially arranged, and the microstrip cathode (101), the anode mesh (102), the MCP image intensifier tube (104), and the CCD are coaxially arranged. A magnetic focusing lens (103) is located between the anode mesh (102) and the MCP image intensifier tube (104). The CCD is used to display a measurement light spot image, and analyzes and processes the measurement light spot image to obtain a detection waveform. The electron beam oscilloscope having improved temporal resolution uses a pulse voltage to cause electron energy dispersion, and the energy dispersion improves the temporal resolution of electron beams. The magnetic focusing lens (103) is utilized to generate a Gauss magnetic field, and the magnetic field forms images of the photoelectrons on the microstrip cathode (101) at the MCP image intensifier tube (104), thereby improving the imaging quality of the oscilloscope while enabling the measurement of electrical pulse waveforms.
